Hey Jake, this error usually happens when your ipsw is corrupted. I'd recommend you to download the firmware you want to update to. Then on iTunes while you're clikcing the restore button click the option key if you're on a Mac or the alt key if you're on pc and then choose the ipsw you downloaded and it should restore to that iOS: Also try this and this.

What on earth is one to do when you've already ERASED the iphone/factory reset it.....and you're trying to recover, and NOW you're getting the Error 48 message??? I get almost completely thru the Recovery process, then when it gets to the firmware stage, I stopped cold with the 48 error. But with an already erased iPhone that obviously cannot get to my Home Screen, or go online (all it can do is hook up to iTunes, via another

computer), I do not know a method by which I would be able to access that firmware.....even if it is the problem behind all this.

Over the years we’ve had a few SmartPhone Recovery PRO customers contact us asking how to fix an iPhone stuck in recovery mode. As it appears to be a common problem (even among some of us here in the office), we thought we’d share a few methods of how to kick an iPhone out of recovery mode.

An iPhone can sometimes get stuck in recovery mode if:

You intentionally activated recovery mode to solve a problem

You’re trying to jailbreak your iPhone and it all went terribly wrong

Like many of us – you were simply trying to update to the latest iOS software

Here are our suggested methods of recovery if your iPhone is stuck in recovery mode:

Option A – Tiny Umbrella

Option B – iTunes Restore

Typically if your iPhone is stuck in recovery mode, this automatically means you have to kiss goodbye your current iPhone data and settings. The general method of recovery for an iPhone stuck in recovery mode is an iTunes restore – great if you have recently performed an iTunes backup, tragic if you have not. If your last iTunes backup was a while ago, you risk losing any data added to your device since your last iTunes backup. However, there is now a software that claims to get your iPhone out of recovery mode, without causing data loss (this method has also been known to work on a pesky iPad or iPod Touch stuck in recovery mode). Just follow the steps below to kick your device out of recovery mode. If you’d rather stick to the traditional iTunes method of recovery, scroll down to Option B and follow the prompts to recover any data obtained after your last iTunes backup.

Updating my 4S to IOS 8.4 was not succesful. Recovery using Itunes gave an Error 48.

Only fools do things over and over again and expect a different outcome.

So there I was being a fool trying recovery after recovery as suddenly I had an idee.

In my opinion there are 3 main factors: the hardware, the software and the test to make sure everything is working properly.

Hardware suddenly broke during update? I don't think so.

Software not OK? Not likely as the same software is already on millions devices.

Test not OK? Probably!

As I noticed being a fool, the Iphone was preparing, installing and testing and just before finishing gave Error 48. So the next time I tried, after the installation was finished and testing was about to end, I simply pulled the connection cord with my macbook and thus with Itunes. Now the testsoftware in Itunes, couldn't tell my Iphone he was not OK and he started just like that and is working properly ever since.

In this case, the patient was sic just because the doctor told him he was.

Maybe, there is something somewhere not 100% Ok, but if I can make calls, read mail, surf the net, use whatever app I tried so far, it is just a perfect working Iphone to me.

Put Iphone in recovery mode. Connect to Itunes, follow steps to restore, device will get the software, unpack it, install it, restore firmware and than start testing. The progression bar will jump to the end and stay there for a while and then will give Error 48. Just unplug the device before the error appears.

Before I did this I tried everything from dfu mode to uninstalling and reinstalling Itunes. Hard to give a detailled description and as you will understand, I will not try if I can do it again on my Iphone. If it ain't broke, don't fix it

I'm glad it worked for you but it didn't for me. After restoring the firmware that's it for me. No testing or anything. I tried unplogging in many different times but it just doesn't work. Thanks anyway.
